Description

  The present invention relates to an operation status monitoring program that gives a computer a function for monitoring operation information of a program executed on the computer.

  In many private companies / local governments that use computers for business, new programs are added according to changes in business and organization, and deleting existing programs involves risks, so over time The number of programs tends to increase. However, even if the number of programs increases, there may be only a part of the programs that are actually running in business. In such a case, there is a problem that maintenance costs are paid for a program that is not actually used, and the capacity of the storage apparatus is wasted.

  For this reason, conventionally, there has been proposed a method of monitoring the operating status of programs included in the system and listing programs that are not operating as deletion targets. For example, Patent Literature 1 includes information on processes executed by an operating system by collecting information using a program interface and monitoring process execution status, and information collected by the monitoring means. An operation status monitoring device is disclosed that includes a generation unit that aggregates process execution statuses of application software and generates operation results of the application software.

JP 2004-259036 A Paragraph 0014

  However, the conventional apparatus as disclosed in Patent Document 1 can monitor the operation status only in process units or program units, and the part actually used for business is only a part of the program. There is a problem that there is no choice but to leave programs that are mostly unused. Monitoring the operating status in units of processes and programs as described above is not sufficient for effective use of storage devices and improvement of program execution speed. Understanding the operating status in steps of source programs Is required.

  If it is necessary to monitor the source program step by step, the programmer has traditionally analyzed the source program on the desk, investigated the line executed by embedding the trace program in the operating system, or , I was investigating a precise running address by CPU emulator. However, both methods involve technically very difficult tasks, and it was difficult for a user who is not an advanced computer expert to implement.

  The present invention has been made in view of the above-described problems of the prior art, and the problem is that even a user who is not an advanced computer expert can easily determine the operation status of a program in steps of a source program. An object of the present invention is to provide a program that causes a computer to function as an apparatus that can be monitored.

  An operation status monitoring program according to the present invention is a program for monitoring the operation status of a program executed by a computer in order to solve the above-described problem, and translates a source program into a machine language and stores the program in a computer. Detected machine with reference to a detection function that detects the execution of machine language instructions included in execution modules mapped in space, and a definition list that stores correspondence information between each step of the source program and machine language instructions of the execution module Of the step specified by the step position specifying function in the data table for the operation status map that defines the correspondence between each step of the source program and the number of executions in units of steps. Update the operating status map data table by adding the number of executions According to the number of executions of the step corresponding to the display pattern of each unit graphic based on the new function and the unit graphic corresponding to each step in a one-to-one correspondence side by side and stored in the data table for operation status map It is characterized by realizing an output function for outputting an operation status map in which the execution frequency for each step can be visually recognized by changing.

  Although the above definition list may directly associate the correspondence between the steps of the source program and the machine language instructions of the execution module, the load obtained by translating each step of the source program and the source program into the machine language It is more versatile if it is composed of two lists: a linkage list that defines the correspondence with the relative addresses of the module machine language instructions, and a mapping list that defines the absolute addresses in the memory space where the execution modules are mapped. . In the latter case, the step position specifying function refers to the mapping list based on the absolute address of the executed machine language instruction, specifies the program including the machine language instruction, and determines the absolute address at the beginning of the execution module from the absolute address. A step corresponding to the machine language instruction can be specified by referring to the linkage list based on the relative address obtained by subtracting the address.

  Furthermore, in the case of a dynamic allocation program in which the absolute address in the memory space to which the execution module is mapped is dynamically defined, as the above definition list, a dynamic mapping list holding dynamic mapping, a source program If a linkage list that defines the correspondence between each step and the relative address of the machine language instruction of the load module obtained by translating the source program into machine language is prepared, the step location specifying function can execute the executed machine language instruction. Relative obtained by referring to the dynamic mapping list based on the absolute address of the program, identifying the program containing the machine language instruction, and subtracting the absolute address of the execution module dynamically allocated from the absolute address Refers to the linkage list based on the address and identifies the step corresponding to the machine language instruction. Rukoto can.

  The operating status monitoring program of the present invention includes an extraction function for extracting a step whose number of executions is less than or equal to a predetermined value from the operating status map data, information for specifying the extracted step, and the step. It is desirable to further realize a list output function for outputting a list of information for specifying programs.

  In the output function, it is desirable to display an operation status map on a display connected to a computer and change the luminance or color of the unit graphic according to the number of executions. The operating status map may be printed out on paper.

  Furthermore, the operation status monitoring program of the present invention distinguishes unit graphics corresponding to all steps of a program including the step from unit graphics corresponding to steps of other execution modules when an arbitrary step is designated. It is desirable to include an identification display function for displaying as possible.

  According to the program of the present invention configured as described above, the number of executions can be counted in step units of the source program during the actual operation of the computer, and this can be output in a visible form. Even the user who is not at home can easily monitor the operation status of the program in steps of the source program. Therefore, it is possible to provide a judgment material for correcting or deleting a program in units of steps. In addition, since the daily operating status can be monitored in real time, unnecessary programs and unused steps can be deleted at any time.

  In addition, when the definition list is divided into a mapping list and a linkage list, the mapping list has a configuration specific to the computer, but the linkage list is common to the program and is executed on another computer. Can also be used. As such a linkage list, the one output from the translation program when the source program is translated (compiled and linked) into the machine language can be used.

  When the extraction function and the list display function are provided, steps with a low execution frequency can be automatically extracted and presented to the user. The user can delete unnecessary steps based on the list or review the logic of the program.

  Furthermore, when an identification display function is provided, it is possible to easily determine in which program a specific step is included in the program from the operation status map. Therefore, when a place where there is no access or where a small number of steps are concentrated is found on the operation status map, it is possible to easily determine which program these steps are, and the operation of each program unit. The situation can be grasped and used as a criterion for deletion judgment.

  DESCRIPTION OF EMBODIMENTS Hereinafter, an embodiment of an operation status monitoring program according to the present invention and an operation status monitoring apparatus to which the program is applied will be described with reference to the drawings. First, an outline of a computer system to which the operation status monitoring program of this embodiment is applied will be described based on FIG. As shown in FIG. 1, this computer system includes a monitored computer 10 connected to each other via a network or parallel or serial communication, and an operating status monitoring device (computer) for monitoring the operating status of the monitored computer. 20.

  The monitored computer 10 includes a CPU 11, a hard disk (HD) 12, a memory (RAM) 13, and a communication adapter 14 connected to the CPU 11. The HD 12 includes an operating system 12a, a program counter read processing unit 15 that sequentially reads the value of the program counter 11a that counts the logical address of the machine language instruction executed by the CPU 11, a dynamic arrangement program information table 12b, Application program 12c is installed. When the monitored computer 10 is activated, the CPU 11 reads the operating system 12a from the HD 12 onto the RAM 13 and executes it, and activates the program counter read processing unit 15 and the application program 12c necessary on this operating system.

The operating system 12 a manages a logical memory space obtained by expanding a limited physical memory area of the RAM 13 by using a predetermined area of the HD 12. The conversion between the physical address and the logical address is automatically executed by the operating system 12a. The execution physical address is converted into an execution logical address by the following calculation.
Execution logical address = execution physical address-start physical address of program expansion destination
+ Program start logical address

  The operating system 12a arranges and executes a dynamic allocation program in a logical memory space obtained by expanding a limited physical memory area of the RAM 13, for example, as shown in Table 1 below. The program name and allocation address to be managed are managed in the dynamic allocation program information table 12b. The recording of the program name and the arrangement head logical address is automatically executed by the operating system 12a.

Since only the logical address needs to be considered on the application program side, the following description is based on the logical address with reference to the logical memory space. The program counter 11a is a counter indicating an execution logical address of a machine language instruction executed by the CPU 11. The program counter read processing unit 15 connected to the CPU 11 reads the execution logical address and sends it to the operation status monitoring device 20. Send.
Similarly, the program counter read processing unit 15 reads the dynamic placement program name and the placement destination logical address in the dynamic placement program information table 12b and transmits them to the operation status monitoring device 20.

  Also, in this specification, code written in a high-level language such as COBOL or C language is a source program, a module obtained by translating (compiling and linking) this into machine language is a load module, and this load module is monitored. Those loaded in the logical memory space of the computer 10 are distinguished as execution modules. In the source program, each step position is represented by a relative step position starting from the head of the source program. In the load module, each machine language instruction position is represented by a relative address starting from the module head. The machine language instruction position is represented by an absolute address starting from the beginning of the logical memory space. Note that addresses that contain the characters “logical address” such as “execution logical address” and “start logical address” indicate absolute addresses in the logical memory space, and are distinguished from relative addresses that indicate addresses in the load module. The

  The operating status monitoring device 20 includes a CPU 21, an HD 22 connected to the CPU 21, a RAM 23, a communication adapter 24, and a display 25. An operating system 22a and an operation status monitoring program 22b for monitoring the program operation status of the monitored device 10 are installed in the HD 22, and a mapping list 22c and a mapping list 22f used for the operation status monitoring program are provided. An operating status map data table 22e for recording the list 22d and the output of the operating status monitoring program 22b is stored.

  The mapping list 22c and the linkage list 22d correspond to a definition list that defines the correspondence between each step of the source program and the machine language instruction of the execution module. The mapping list 22c defines an absolute logical address in the memory space to which the execution module is mapped. For example, as shown in Table 2 below, each execution module executed by the monitored computer 10 has a mapping list 22c. It defines the start logical address and end logical address of the expansion destination in the logical memory space.

  On the other hand, the linkage list 22d defines the correspondence between each step of the source program and the relative address of the machine language instruction of the load module obtained by translating the source program into the machine language. It is defined for each program. For example, a linkage list 22d as shown in Table 3 below is prepared for the program AAAA in Table 2 above. The list includes the start relative address and end relative address of the machine language instruction corresponding to each step, the relative step position where the start step is 0, and the total number of steps. Since one step of a source program usually corresponds to multiple lines of machine language instructions, the start and end relative addresses are defined as shown below to indicate the range of machine language instructions corresponding to each step. Yes.

  The operating status monitoring program 22b uses the mapping list 22c and linkage list 22d described above to determine which of the operating status monitoring programs 22b is executed based on the execution logical address output from the program counter read processing unit 15 of the monitored computer 10. Identify which step in the source program. That is, by referring to the mapping list 22c based on the execution logical address, it is possible to specify a program including the machine language instruction assigned to the execution logical address. The step corresponding to the machine language instruction can be specified by referring to the linkage list 22d based on the relative address obtained by subtracting the top logical address of the execution module from the execution logical address.

  In the case of a program in which a load module is dynamically allocated in the memory space at the time of execution, the operation status monitoring program 22b is dynamically updated as shown in Table 4 below in order to manage the address of the allocation destination in the memory space. A mapping list 22f is prepared. Based on the execution logical address output from the program counter read processing unit 15 of the monitored computer 10, the dynamic mapping list 22 f is updated in advance, and later based on the execution logical address output from the program counter read processing unit 15. By referring to the dynamic mapping list 22f, the program including the machine language instruction assigned to the execution logical address can be specified. Then, the step corresponding to the machine language instruction can be specified by referring to the linkage list 22d based on the relative address obtained by subtracting the execution module arrangement head logical address from the execution logical address.

  The operating status monitoring program 22b counts the number of executions for the specified step, saves the result in the operating status map data table 22e, and displays the result on the display 25 as shown in FIG. The operating status map M is displayed. The operation status map data table 22e stores the number of executions for each step of the source program for all execution modules defined in the mapping list 22c and the dynamic mapping list 22f. As shown, the absolute step position assigned as a unique serial number throughout all source programs including dynamic allocation programs, the relative step position assigned to each source program, and the number of executions per step are associated with each other. Is recorded. In Table 5, the steps included in the program AAAA in Table 2 are surrounded by double lines.

  The operation status map M displays square unit graphics one-to-one corresponding to each step in a grid and displays the display pattern of each unit graphic based on the contents of the operation status map data table 22e. By changing according to the number of executions, the execution frequency for each step can be visually recognized. In this example, as shown in FIG. 2, the brightness of each unit graphic (shown by shading in the drawing) is changed according to the number of executions. In addition, as a change of the display pattern, not only the brightness of the gray scale but also the color may be changed or the blinking frequency may be changed. In addition to being displayed on the display 25, it may be printed out on paper from a printer (not shown).

  The unit graphic of the operation status map M corresponds to the absolute step position shown in Table 5, and is arranged so that the absolute step position increases from top to bottom and from left to right in the figure. That is, as shown in FIG. 3, the unit graphic at the upper left corner corresponds to the step at the absolute step position 0, and the unit graphic at the upper center edge corresponds to the step at the absolute step position 30000. The user can check the execution frequency in units of steps by looking at the operation status map M displayed on the display 25.

  When the user designates a specific step on the operation status map M, for example, a step with a low execution frequency, the operation status monitoring program 22b includes a step corresponding to the specified unit graphic as shown in FIG. All steps of the execution module are displayed in a frame F so that they can be distinguished from the steps of other execution modules, and the program name is displayed as a label L in the map. Thus, the user can easily determine in which program the specified step is included, and can grasp the operating status of each program unit and use it as a criterion for determination of deletion. The step may be designated on the screen using a pointing device such as a mouse, or the absolute step position may be designated by a numerical value.

  Next, the flow of processing executed by the monitored computer 10 and the operation status monitoring device 20 according to the embodiment will be described based on the flowcharts shown in FIGS. 4 and 5 show the processing of the monitored computer 10, and FIGS. 6 to 14 show the processing contents of the operating status monitoring program 22b executed on the operating status monitoring device 20. FIG. 6 to 11 show processing for displaying an operation status map on the operation status monitoring device 20 side, and FIGS. 12 and 13 show a predetermined number of executions from the operation status map data on the operation status monitoring device 20 side. FIG. 14 shows a process related to a list output function that extracts information for specifying a program by extracting a step below a specified value, and FIG. 14 relates to an identification display function for displaying an execution module including a specified step so as to be distinguished. Indicates processing.

The program counter read processing unit 15 of the monitored computer 10 reads the execution logical address of the program counter 11 a and transmits it to the operating status monitoring device 20. That is, as shown in FIG. 4, the program counter read processing unit 15 waits for an address to be written to the program counter 11a (S001), and if it has been written, reads the execution logical address of the program counter 11a ( S002), and transmits to the operation status monitoring device 20 (S003).
Further, as shown in FIG. 5, the program counter read processing unit 15 waits for the dynamic placement program name and the placement destination logical address to be written in the dynamic placement program information table 12b (S011), and there is a writing. In this case, the dynamic placement program name and the placement destination logical address in the dynamic placement program information table 12b are read (S012) and transmitted to the operation status monitoring apparatus 20 (S013).

  As shown in FIG. 6, the operating status monitoring program 22b of the operating status monitoring device 20 waits to receive an execution logical address issued from the monitoring computer 10 (S101), and reads it when received (S102). Subsequently, the subroutine of the step position specifying process (S103) shown in FIG. 9, the operation status map data updating process (S104) shown in FIG. 10, and the corresponding step position display process (S105) shown in FIG. The process of S101 corresponds to a detection function that detects the execution of a machine language instruction. 9 is a step position specifying function for specifying a step corresponding to the detected machine language instruction, the process of FIG. 10 is an update function for adding the number of times of execution of the specified step, and the process of FIG. This corresponds to the output function for outputting the operation status map.

  In addition to the above, the operation status monitoring program 22b waits to receive the dynamic allocation program name and the allocation destination logical address issued from the monitoring computer 10 as shown in FIG. When it is received, it is read (S112). Subsequently, the subroutine of the dynamic mapping list update process (S113) shown in FIG. 8 is executed.

  The dynamic mapping list update process shown in FIG. 8 determines whether or not the placement destination logical address read in S121 is already stored in the dynamic mapping list 22f from the head of the program shown in Table 4 to the placement head logical address. Determine whether it is included in the range between the end logical address (S122, S123), and if stored, determine whether the logical address has been assigned to another dynamic allocation program (S124) Thus, the information stored in the dynamic mapping list 22f is updated. When updating the information, first, the end relative address is read from the linkage list corresponding to the dynamic allocation program (S125). An address W_add obtained by adding the read end relative address to the placement destination logical address is calculated (S126), and the dynamic placement program name, placement destination logical address, and address W_add are set in the dynamic mapping list 22f (S127). Since the same program may be arranged at a plurality of addresses, information can be added without omission if it is the above-described system that works if the arrangement start logical address is different.

  The step position specifying process shown in FIG. 9 is a process for specifying a step on the source program corresponding to the execution logical address read in S102. First, the variable “total number of searched program steps S” used for calculation is reset to 0 (S201), and the mapping list 22c is searched using the read execution logical address X_add (S202). Here, it is determined whether or not the execution logical address X_add is included in the range between the start logical address and the end logical address of the program from the top of the program shown in Table 2 (S203). In this case, the total number of steps of the program is added to the total number S of searched program steps (S204), all the programs in the mapping list 22c are searched (S210), and the processes of S202 to S204 are performed until a program matching the range is found. Repeat the process.

  When a program corresponding to the execution logical address is found, the operation status monitoring program 22b extracts the program name from the mapping list 22c shown in Table 2 (S205), and to which step of the program the execution logical address corresponds. In order to determine, the head logical address of this program (execution module) is subtracted from the execution logical address X_add to obtain a relative address Y_add (S206). At this time, the dynamic arrangement program display is set to OFF in order to process a fixed arrangement program that is not dynamic arrangement in the process of FIG. 10 (S216). Then, the linkage list 22d is searched in the order of steps using the obtained relative address Y_add (S207), and whether or not the relative address Y_add falls within the range between the start relative address and the end relative address of the linkage list 22d. Judgment is made (S208). The processes of S207 and S208 are repeated until the condition of S208 is satisfied. When a step having a relative step position within the range is found, the relative step position of that step is extracted from the linkage list 22d (S209), and the process returns to the process of FIG. .

  If there is no program in the mapping list 22c under the condition of S210, the dynamic mapping list 22f is searched using the execution logical address X_add read as the dynamic allocation program (S211). Here, it is determined whether or not the execution logical address X_add is included in the range between the placement start logical address and the placement end logical address of the program from the head of the program shown in Table 4 (S212). The processes of S211, S212 are repeated until the condition is satisfied, and when a program whose execution logical address X_add is within the range is found, the program name is extracted from the dynamic mapping list 22f (S213), and this program is executed from the execution logical address X_add. The placement start logical address of (execution module) is subtracted to obtain the relative address Y_add (S214). At this time, in order to process the dynamic placement program in the processing of FIG. 10, the dynamic placement program display is set to ON (S215), and the processing is performed from S207.

  The operating status map data update process shown in FIG. 10 is a process for updating the number of executions of the operating status map data table 22e shown in Table 5 for the step specified by the step position specifying process. The dynamic placement program display set to ON or OFF in S215 or S216 is determined (S305), and in the case of OFF (Yes), the relative step position specified by the step position specifying process is converted to an absolute step position. The total number of searched steps S is read (S301), and the relative step position is read (S302). If it is ON (No) in the condition determination of S305, the head position of the absolute step position where the program name matches the dynamic placement program is obtained from the operation status map data table 22e and set to the total number S of searched steps. (S306). Since the sum S indicates the absolute step position at the beginning of the source program including the executed step, the absolute step position of the step is specified by adding the relative step position to this (S303). Then, 1 is added to the number of executions of the identified step (S304). Thereby, the operation status map data table is updated.

  Subsequently, in the corresponding step position display processing shown in FIG. 11, the absolute step position is obtained by adding the relative step position to the total number S of searched steps (S401), and the access count X of the step is obtained from the operation status map data. Reading (S402), the luminance corresponding to the execution number X is determined based on the luminance chart shown in FIG. 2 (S403), and the unit graphic of the corresponding step of the operation status map M is set to the determined luminance (S404).

  By repeating the processes shown in FIGS. 5 to 11, the number of executions in the operation status map data table 22e is updated each time a program step is executed, and the operation status map displayed on the display 25 is displayed. The brightness of the unit graphic of M changes. The user can grasp the operation status of the program installed in the monitored computer 10 in units of steps by executing the above processing for a predetermined time.

  Next, a process for extracting a step whose number of executions is equal to or less than a predetermined number using the operation status map M displayed on the display 25 will be described with reference to FIGS. First, the user sets the number of executions Y that is the extraction threshold (S501). The operating status monitoring program 20b searches the operating status map data table 22e step by step in the arrangement order based on the number of executions Y (S502).

  That is, the number of executions of the target step is read from the operation status map data table 22e, and it is determined whether or not this is less than or equal to the threshold value Y (S503). If it is equal to or smaller than the threshold value, the absolute step position is extracted from the operation status map data table 22e (S504), and the program name specifying process shown in FIG. 13 is executed (S505). This process will be described later. When the program name is specified, the program name and the number of execution times of the corresponding step are held (S506), and the relative step position of the corresponding step is extracted from the operation status map data table 22e and held (S507). When the number of executions is larger than the threshold Y (S503, No), the processing for specifying the steps in S504 to S507 is skipped. The processes of S502 to S507 are executed for all the steps registered in the operation status map data table 22e, and all the steps whose number of executions is equal to or less than the threshold Y are extracted.

  When the execution count check is completed for all the steps registered in the operation status map data table 22e (S508, Yes), the stored program name, relative step position, and execution count are all read (S509, S510, S511). . Then, a list of the read program name, relative step position, and number of executions is output (S512). The list may be displayed on the display 25 or printed out on paper. The user can eliminate the redundant part in the individual source program by reviewing the logic including this step for the step with few execution times referring to this list, or deleting the step with zero execution number. It can be used as a document to do.

  In the program name specifying process executed in S505, as shown in FIG. 13, it is a process for specifying in which program the absolute step position extracted in S504 is a step. First, the searched program step total number S is reset to 0 (S601), and the absolute step position is read (S602). Next, the mapping list 22c is searched in the arrangement order, and the total number of steps of each program is sequentially extracted from the linkage list 22d by one program (S603).

  Then, the total number of steps of one extracted program is added to the searched program step number sum S (S604), and it is determined whether or not the absolute step position is smaller than the sum S (S605). The absolute step position is larger than the total number of steps of the program arranged before the program including this step, and smaller than the total number of steps of the program including this step. Therefore, if it is determined whether or not the absolute step position is smaller than the total sum S while adding the total number of steps in units of programs as described above, the absolute step is added to the last added program when it becomes smaller. It turns out that the step indicated by the position is included. Therefore, the program name of this program is extracted from the mapping list 22c (S606), and the processing returns to FIG.

  Next, the program position display process shown in FIG. 14 will be described. This process includes this step by executing the monitoring side display process shown in FIG. 5 and specifying a unit graphic corresponding to a specific step in a state where the operation status map M is displayed on the display 25. This is a process for displaying the range of the program on the map and the program name.

  The processing of S701 to S707 for specifying the program name based on the absolute step position is the same as the program name specifying processing shown in FIG. However, in the process of FIG. 14, in order to specify the absolute step position indicating the head of the program, the value of the searched program step total S before adding the total number of steps of the program is stored in the work W. Processing has been added.

  When the program name is extracted in S707, the absolute address position saved in the previous work W is taken as the absolute address position at the beginning of the program, and the absolute address position represented by the sum S including the total number of steps of the program is The final absolute address position of the program is set (S708). Then, the unit graphic corresponding to the first absolute address position on the operation status map M to the unit graphic corresponding to the final absolute address position is enclosed in a frame F as shown in FIG. 3 (S709), and the program name is labeled. L is added to the frame (710). As a result, the user can confirm the program range including the step represented by the absolute step position and the program name by the operation status map M displayed on the display 25, and grasp the operation status of each program. Thus, it can be used as a criterion for deletion determination.
